nar-Drs'rnran'mn non oooxme UTENSILS'.

Heretofore in cooking and preparing food in pots,

l saucepans, stew-pans and like vessels, the material therein contained has been liable to adhere to the bottom of the vessel and then to become burned due largely to the direct contact of the sides and bottom of the vesel with the fire or flame employed, which also if too intense may cause .the contents of thevesscl to boil over." i

I Now the object. of my invention is to overcome these difliculties by providing a heat distributor adapted to intervene between a vessel, used for cooking purposes and the fire or flame employed and so constructed that direct heat cannot come in contact with the sides or bottom of a vessel but is distributed evenly over the entire extent of these sur'faces'whereby the food is I cooked uniformly throughout and burning of the same .is prevented, and furthermore, this is accomplished without resorting to a constant stirring of the material being cooked.

In carryingout myinvention, I preferably employ a plurality of plates made of sheet metal or other similar material and each provided with series of apertures so placed that when the parts are assembled the said aperturslin one plate are out of line with or do not register. with those in the next adjacent plate, means for seeming the said plates together and means for supporting a cooking utensil above the top plate, as here-" inafter mdre particularly described.

In the'drawing, Figure 1 is a plan viewoimyiimproved heat distributor, Fig. 2 is a sectinbn'line x, x, of Fig. lgFig. 3 isa partial section illustrating the modi- 40 fled formofmy invention and Fig. 4 is an elevation of the distributor illustrating the use of the same with an auxiliary frame shown as broken away for using the heat distributenas' will behereinafter described.

y a, b,'dsignate flat-plates which may conveniently be 25 made of sheet metal'or other similar material and circular in outline as illustrated, or of other configuration as circumstances may require.

The plate a is provided atits periphery with an overturned annular flange 2 preferably integral therewith Q0 and at its periphery the plate bis provided with a simi- Ian annular flanges 3; the plate a with its annular flange 2 being ofisu ch dimensions as to fit tightly within the annular flange 3 of the plate b, by which means the said plgtes 'aresecured together. It will be manifest Specification of Letters Patent. A nmnn and August 26,1906. Serial No. 331,986.

however, that other meansto this end may be employed without departing from the nature of my invention.

. The plate a is provided with a series of holes or apertures indicated at c. Preferably these apertures c are arranged in concentric circles and are equally spaced apart. Similarly the plate b is provided with a series of holes or apertures indicated at d, which with the oxception of the central aperture are also arranged in concentric circles and equally spaced apart; holes 0 in the plate a and holes d in the plate b being so situated that. they are staggered in their relationship to one another, that is to say, the holes in one plate are not in line with those in the other when the said plates are secured together. The upper plate a may also be provided with a series of pins or projections 2 preferably arranged in radial lines as illustrated, and adapted to support a vessel in which food is to be cooked. I also employ, as illustrated, a ring f pivotally connected to a strap 4 which is riveted at 5 to the upper plate a; the ring f being employed to conveniently handle the heat distributer and also as a means for supporting the same when not in use.

As indicated in Fig. 2, any improved heat distributor is preferably of such a diameter as to fit within the op eiiing in the top (S of a stove or range normally cov ered by a stove lid. As shown in Fig.3, I may employ an. intermediate plate In this instance the holes or apertures in the exterior plates are preiombly placed in similar positions, while the holes h in the intense diate plate {I are placed in positions intermediate of those in the exterior plates (1., b. I

In some instances, such for instance as making toast or where it is required to boil 2. material very slowly, it may be necessary to employ an auxiliary stand indi-' cated at 7 of Fig. 4; this stand being prelerably cyliudrical and provided with a base 8 and a top flange 9 adapted to receive the heat distributor in order to place the same at a greater distance from the fire or flame employed incookiug.

It will be manifest from the construction of the article hereiubefore described that the flames or heated air from the lire must first pass through the apertures in the lower plate and be reflected by striking the upper plate before passing througlrlbo apertures in the same to reach the bottom of the vessel in which food is 10 to be prepared, and that by thus regulating the heat an even distribution of the same is obtained. I

I claim as my invention: 1. A heat dlstr ibuter for cooking utenslls. comprising two parallel spaced apart plates of similar outline and each provlded with series of apertures and menus for securing said plates together at thelr peripheries in their spaced apart relation so as to form a chamber entirely lnclosed between the said plates and the said means.

2. A heat distributer for cooking utensils, comprising two spuoednpart plates of similaroutline; each of which is provided with :1 series of apertures so placed that the I said apertures in one plate are outfit-line with those in the other plate, means for securing the said plates together and means for supporting a cooking utensil ahove the topplate.

.A heat distributer for cooking utensils, comprising t1 top plate, an annular flange integral with the same, a bottom plate, and an annular flange integral with the said bottom plate and adapted to receive the said annular flange of the top plate so that said plates occupy a parallel relation, and said plates being provided with a series of apertures so placed that those in one plate are out of line with those in the other plate.

.4. A heat distrihuter for cooking utensils, comprising a to plate, tan-annular flange integral with the same, a bottom plate, oil-annular flange integral with the said bottom plate and adapted to receive the said annular flange of the top plate so that-said plutes occupy a 'parailel relation,-

and said plates being provided with a series of apertures so placed that those in one plate are out of line with those'in the other plate and means for supporting a cookof the top plate so that said plates occupy's parallel relation, 'und said plates being providedtvith a series of -aper- Lures so placed that those in one plate a'reout of line with those inthe other plate zindca series of pins secured in radial positions in said top plate and adopted to support a cooking utensil thereon. v
